Commit dd74b945af2e ("ARM: uniphier: use pr_() instead of printf()
where appropriate"), but I missed to update this file for some reason.

Replace printf() with pr_() to specify proper loglevel.

It has been a while since ARM Trusted Firmware supported UniPhier SoC
family. U-Boot SPL was intended as a temporary loader that runs in
secure world. It is a maintenance headache to support two different
boot mechanisms. Secure firmware is realm of ARM Trusted Firmware
and now U-Boot only serves as a non-secure boot loader for UniPhier
ARMv8 SoCs.

Fix warnings reported by sparse:
- ... was not declared. Should it be static?"
- cast to restricted __be32
While fixing those, the type conflict of cci500_init() was found.

If the DRAM clock duty does not meet the allowable tolerance,
it is marked in an efuse register. If the register is fused,
the boot code should compensate for the DRAM clock duty error.

This parameter is redundant because we can know the number of

Just cosmetic changes:
- Rename prefix DMPHY_ to MPHY_ for consistency
- Move UMC parameters below for complete decouple of PHY and UMC
- Remove redundant whitespaces

It seems more readable to use arrays to get SoC specific parameters
instead of the crappy switch statement.

The two arrays ddrphy_{op,ip}_dq_shift_val, occupy more than 3.8 KB
memory footprint, which is significant in SPL.
There are PHY parameters for 5 boards, but they are actually not
board specific, but SoC specific. After all, we just need to have
2 patterns, for LD20 and LD21. Also, the shift values are small
enough to become "short" type instead of "int". This change will
save about 3 KB memory footprint.

Currently, uniphier_get_soc_type() converts the SoC ID (this is
read from the revision register) to an enum symbol to use it for SoC
identification. Come to think of it, there is no need for the
conversion in the first place. Using the SoC ID from the register
as-is a straightforward way.

These files only need error number macros. Actually, IS_ERR(),
PTR_ERR(), ERR_PTR(), etc. are not useful for U-Boot. Avoid
unnecessary header includes.

The ddrphy_shift_rof_hws() never writes back the shifted delay value
to the register, which makes this function non-effective.

Add the LD11 SoC data and adjuts the printf() format because this is

Do not hard-code the number of DX blocks because it is a different

The DDR PHY register view of LD11 is slightly different from that
of LD4/Pro4/sLD8, but it will be possible to share the register
macros (and I want to re-use as much code as possible). Change
the code in the more flexible form.

This does not have much impact on behavior, but makes code look more
more like Linux. The use of devm_ioremap() often helps to delete
.remove callbacks entirely.

The ifdef conditionals in header files prevent us from multi-SoC

The current CONFIG names like "CONFIG_ARCH_UNIPHIER_PH1_PRO4" is too
